Longitudinal section microstructure of the samples. a μg sample and b 1g sample. From the bottom up, the red dash dot lines indicate the positions of the initial solid–liquid interfaces, the blue dashed lines indicate the positions and shapes of the transition interfaces, and the blue dashed lines with arrows indicate the growth directions of the grains. The diameter of the samples is about 6 mm
